Decimal # as _ tuple():as _ tuple()是一个 Decimal 类方法，返回 Decimal 值的命名元组表示。
语法: Decimal.as_tuple()
参数:十进制值
返回:元组，值为 –符号 –数字 –指数
代码# 1:as _ tuple()方法示例
# Python Program explaining
# as_tuple() method
# loading decimal library
from decimal import *
# Initializing a decimal value
a = Decimal(-1)
b = Decimal('0.142857')
# printing Decimal values
print ("Decimal value a : ", a)
print ("Decimal value b : ", b)
# Using Decimal.as_tuple() method
print ("\n\nDecimal a with as_tuple() method : ", a.as_tuple())
print ("Decimal b with as_tuple() method : ", b.as_tuple())
输出:
Decimal value a : -1
Decimal value b : 0.142857
Decimal a with as_tuple() method : DecimalTuple(sign=1, digits=(1, ), exponent=0)
Decimal b with as_tuple() method : DecimalTuple(sign=0, digits=(1, 4, 2, 8, 5, 7), exponent=-6)
代码# 2:as _ tuple()方法示例
# Python Program explaining
# as_tuple() method
# loading decimal library
from decimal import *
# Initializing a decimal value
a = Decimal('-3.14')
b = Decimal('321e + 5')
# printing Decimal values
print ("Decimal value a : ", a)
print ("Decimal value b : ", b)
# Using Decimal.as_tuple() method
print ("\n\nDecimal a with as_tuple() method : ", a.as_tuple())
print ("Decimal b with as_tuple() method : ", b.as_tuple())
输出:
Decimal value a : -3.14
Decimal value b : 3.21E+7
Decimal a with as_tuple() method : DecimalTuple(sign=1, digits=(3, 1, 4), exponent=-2)
Decimal b with as_tuple() method : DecimalTuple(sign=0, digits=(3, 2, 1), exponent=5)
